How to use

Mount the tail light on the rear of the trailer with the lens facing rearward and the correct orientation. Switch off the vehicle electrical supply before making connections. Wire each chamber to the corresponding circuit on the trailer harness following local wiring conventions (tail/position, stop, indicator and the fourth function where applicable). Mechanically secure the unit with appropriate fasteners and protect electrical connections from moisture. After installation, test each function (tail/position, brake, indicator and the fourth function) to confirm correct operation.

Recommendations

Check compatibility with your trailer wiring and local road regulations before installation. Use correct fusing, inspect seals and connectors periodically for corrosion or damage, and replace the unit if lenses or housings are cracked. If unsure about wiring or mounting, consult a qualified technician.
